Carbon Sequestration in Native Microalgae under Elevated CO2 Concentrations

The invention focuses on harnessing native microalgae to sequester carbon dioxide (CO2) under elevated CO2 conditions, thereby addressing the problem of greenhouse gas emissions. It provides a solution for utilizing microalgae as a natural carbon sink to mitigate CO2 levels in the atmosphere.

• Quality: High-value product extraction
• Enhanced efficacy: iOMICS-guided metabolic regulation
• Cost advantage: Utilization of microalgal biomass for multiple products
• Shelf life: Sustainable and economically viable model
• Ease of use: Non-GMO modification methods
• Any other: CO2 sequestration and sustainable production

Quality: Microalgae-based carbon sequestration offers a natural and sustainable method for removing CO2 from the atmosphere.
Enhanced Efficacy: Native (non-GMO) microalgae strains exhibit high rates of carbon sequestration under elevated CO2 levels, providing an efficient solution for reducing greenhouse gas emissions.
Cost Advantage: Compared to traditional carbon capture methods, microalgae-based carbon sequestration is cost-effective and requires minimal infrastructure.
Shelf Life: Microalgae biomass can be stored or processed into various products, extending its shelf life and potential applications.
Ease of Use: Implementing microalgae-based carbon sequestration systems is relatively simple and scalable, allowing for widespread adoption.
Sustainability: By utilizing native microalgae, the technology promotes environmental sustainability and contributes to efforts to combat climate change.

The technology has applications in industries and sectors aiming to reduce carbon emissions, including environmental management, carbon capture and utilization, and sustainable agriculture. Potential users include environmental agencies, carbon offset companies, industrial facilities, and research institutions focusing on carbon sequestration and climate change mitigation.

Native microalgae strains and CO2 are the primary raw materials, with CO2 readily available from industrial sources.

Presently, no patents have been filed as most of the technology is laboratory scale (work has been published). Patent applications may be filed to protect intellectual property associated with native (non-GMO) microalgae-based carbon sequestration
